For me, the first and still very best of all ceramic stylers [and my dad is a hairdresser too]. It heats up fast, cools down relatively fast, works wonderfully and lasts a long time. In 11 years, I've bought two such stylers. The first one eventually died after 6 years of daily use, rarely skipping a day, while my second one is still going strong. I have no reason to recommend any other styler but this one. My hair is long and very fine.

New without original packaging. Glimmering gold accents and plates and an enhanced design give the ghd gold V classic styler a luxe feel. Smoother gold plates glide effortlessly through the hair to make straightening on all hair types and lengths even quicker and easier, while their contoured edges help to create perfect curls and waves, all with a high shine, salon-style finish. A handy protective plate guard also allows you to pack up your styler straight after use while an automatic sleep mode is activated if the styler isn't used for 30 minutes. Universal voltage ensures you'll get the same styling performance wherever you are in the world, making this styler a great choice if you travel frequently.

I worked in the hair industry for a while so I've used a lot of high end flat irons and I got to say, this one did not impress me at all. I'd never used a GHD before this btw (none of the stylists I know have one) but I ended up ordering the GHD classic styler--which btw seems to be the same as the "IV styler"--instead of the CHI Turbo due to the fact that at the time, the GHD was on sale and basically the same price yet it offered more versatility (the turbo has a velvet cover so you can't use it to curl).
If you’ve read enough ghd flat iron reviews, then you’ve probably realized the main problem about this ghd flat iron. It’s the fact that it’s so popular that so many people are trying to peddle fake copies. It’s hard to believe that people would try to come up with fake ghd straighteners, but they’re now like Zippo, Louis Vuitton, and other iconic brands. There are so many fakes around!
GHD used to be amazing however now the products are cheaply made. I have had many over the years and now done with them. Every single one of my straighteners just stopped working one day. (conveniently just after the warranty). Unfortunately won't be re-purchasing a GHD unless quality changes. Customer Service also not the same, no longer interested in helping.
This overpriced iron is good if you have naturally fine, soft or wavy hair. If you have coarse, thick hair it will not do the job, or it will take you several passes. This is not unique to the GHD, this applies to ALL CERAMIC straighteners. The Auto shut off and dual voltage is awesome, but it is not worth it if the iron does not provide sleek, durable straight hair. If you have kinky, unruly, poofy hair go with TItanium, hand down!!
